Networking :: Make A Huawei K3715 HSDPA Modem Work In Ubuntu 10.04.1

Jan 20, 2011

I'm trying to make a Huawei K3715 HSDPA modem work in Ubuntu 10.04.1. I plug it in, and it loads two mass storage devices (one CDRom containing the Windows software, and one 2GB drive that appears empty), but I don't really know where to go from here.

Note that I replaced the stock network manager with Wicd, as I find it more reliable in picking up wifi connections. I'm not sure if it's suitable for connecting the HSPA modem though.

I recently got a HUAWEI E1630 HSDPA USB Modem and it was working fine until recently. Recently it starts to drop the connection and in /var/log/messages I can see a pppd error "Protocol-Reject for unsupported protocol xxxx". The protocol number is random. Only way to resume is to unplug and replug the device. The happens very frequently and hence the device is not usable.

To isolate the service provider end, I use the same SIM on a PROLINK HSDPA USB Modem and it works fine. Also I use a different SIM from another service provider in this device and the issue still exists.

I am on Kubuntu 10.10 with all the updates to date. Should I report a bug?

I have a weird problem on my laptop. Everything works okey on PC though.

I'm using kNetworkManager on my OpenSuse 11.2 on PC.

Everything works fine there with the following settings:1. Make a new GSM Connection in kNetworkManager and enter settings there2. Edit etc/sysconfig/network/config file and set .....DNS_Policy from "auto" to ""3. Enter openDNS to /etc/resolv.conf (nameserver xxx.xxx.xxx.xxx)

It works like that on my PC.

I did the same on my laptop. The modem connects fine, but the DNS'es ain't resolved. So skype etc will work, but no pages will open in Firefox for example.

I've been trying for a couple of days now to get the Huawei E1750 to work but have had no luck so far. I've installed the packages usb-modeswitch-1.1.4 and usb-modeswitch-data and have edited the usb-modeswitch.conf to include the following:

i'm running Kubuntu karmic and i've been using a 3G Huawei E1552 modem to connect to the internet, everything was going well when suddenly my modem stopped working. I've tried reconfiguring everything, i even reinstalled kubuntu from scratch with no success.Here's a part of my /var/log/debug

I have a little bit of a prediciment with my Mobile Broadband dongle, even though I know I'm in a 3G area (Dongle Supports 3G connection) my internet still loads at the normal GPRS speeds max of 5kb/s. Is there anyway to change the speed of it or do I have to keep with GPRS at the moment?

For F10 patched. I'm in Honduras. The local cell / Internet provider that covers Guatamala, Honduras, El Salvador, uses an HSDPA modem marked "GBC" and is also known as the "China Bird". It's a black usb stick that looks identical to the option unit, but its definitely not an option modem.

lsusb lists it as 1c9e:1001 with no text after it. It automounts as a disk drive with typical Windows software on it. Nothing ever shows up in /dev/ttyUSB*, as I believe the disk mount causes it to not try mounting it as a modem. Dismounting it also does no good.

I've been trying to get a USB modem stick to work with Karmic.The modem is the ZTE MF626 HSDPA on a Telstra Next G plan.I've followed all the guides and links on the forums:Have deactivated the CD autorun on the USB stick in XP lsusb is showing "Bus 002 Device 003:ID 19d2:0031 ONDA Communication S.p.A." demsg is showing "usb 2-2: GSM modem (1-port) converter now attached to ttyUSB1"This seems stable as well, ie checking periodically it doesn't seem to be disconnecting By the way,the blue light indicating network communication/modem active lights up after the device has been plugged in for a second or so.

When I go through Network Connections and add a new mobile broadband connection, there is nothing listed in the "Create a connection for this mobile broadband device" drop-down on the first configuration screen - all the guides I've read say that it should be listed here, but none say any debug steps if it doesn't.Some other guides for older versions of Ubuntu and earlier versions of the modem reference a "/usr/share/hal/fdi/information/20thirdparty/20-zte-mf626.fdi"file which I don't have.

I have bought a so-called web'n'walk stick, which identifies itself as a "Globetrotter HSDPA Model". I managed to get it identified as a serial device (initially, it is detected as a USB drive), but I fail to get it working.

Some month ago i bought a UMTS / HSDPA Stick "HUAWEI Mobile Connect E160". I worried about getting it running with Ubuntu, but it was freaking easy to get it running. Even less complicated than installing the same device with windows.

It worked some month without any problem and then suddenly, didnt work any more. If i plug the device to my laptop (lenovo x61) unter linux now, i still can click to start the mobile broadband, it trys to connect some time, but shows "disonnected" at the end (dont know the exact message in englisch, because i use german language prompts). The same device still works fine with same hardware with windows vista at all 3 usb ports. I deleted the mobile broadband settings couples of times and made a new one, without any effect to the behavior.

I understand that they don't natively support linux but from what I've learned, they are the most linux friendly wireless broadband provider. There are few success stories about installing them on Ubuntu, Xandros, Linux Mint and OpenSuSE.

I do searched the net and found: [url]

Which says I need to compile to create a huaweiAktBbo but when run, it says 'dev' failed. (Compile succeed though).

I tried kppp but my Huawei USB stick is detected as USB storage and not as a modem, so i need to use usb_modeswitch.

I grab it from [url] and tried to download the source but it seems that SlackBuilds has not updated yet its link (and the slackbuild package). I tried to make and make install the latest source from [url] but I think I forget that switch-data and conf, anyway I have to re-download again.

Do I need libusb? Or slackware 13 already have it? (I just learn while typing this that I forgot to download the switch-data and the conf file)

This is really weird, and I would like just this question answered: I've spent like 2 hours by plugging, unplugging, rebooting, and doing everything I could, but the modem wasn't working. When I did ls /dev/ttyU* it was showing up a list of 6 usb devices.

Code:/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2/dev/ttyUSB3 /dev/ttyUSB4 /dev/ttyUSB5And when I sent the command wvdialconf after looking into all the devices, it didn't recognize any modem.

The thing is, that by the time I was writing here for a solution, I disconnected the modem, and when I reconnected it I did a ls /dev/ttyU* just to copypaste the info, and Voil! there were just 2 devices, and wvdialconf worked out just fine! I would like to know what I was doing wrong, so I make sure it won't happen again.

I recently received my Ubuntu 9.10 CD, Kubuntu 9.10CD and Server Edition. I was recommended to do so by a friend because my computer Running on Windows Vista Home Basic with 512MB RAM has been extremely, unbearably slow for the last month or so I got the CD's yesterday and I ran the Ubuntu CD and everything was fine, I rebooted the Computer and it started up! It was great!! Really quick and responsive and easy to use and i LOVE it's features...

My only problem is my Broadband. I live in Ireland and I have my broadband with o2, it's quick and sufficient for my needs. I have a Huawei E270 usb modem (It's wireless broadband). And it wouldn't Work. I plugged it into my pc with Ubuntu up and running and it opened the File for o2 rather than the Interface for it. When I plugged the modem in there was a green lock symbol on the top right of the screen. Is Ubuntu even compatible with the E270 modem?

I am having desperate problems trying to connect to the net with a Huawei E173 USB modem. I was using Linux Mint 7 which I upgraded to version 9 today to see if that would fix the problem but it made no difference. Basically it seems the only time I can connect to the net in linux is if I use the modem in windows and then restart straight into linux, in that case it sometimes gets recognised and works. So at least I know it can work.

I've been trying loads of stuff like usb_modeswitch I found on the net but none of it has worked. Here is what ls-usb gives me -

[Code]....

I am unable to get any work done without the net and I will not have access to a wired connection til the new year.

I have started using ubuntu 11.04 desktop edition recently. And sadly i dont have an internet connection. I have an USB modem of Huawei. But I cant configure that in ubuntu. Im from india and using Reliance Netconnect 1x EC121 modem. Can anybody please tell me how to configure this modem so that I can connect to the internet? Due to lack of internet connection im not being able to download any updates or codecs. I have started using Ubuntu only 2 days ago..

I have a Huawei E 1550 USB stick modem and I'm trying to consistently get it working with Ubuntu 10.4. Using usb_modeswitch and wvdial I've got the device recognized as both a modem and disk drive and it seems to be working okay. wvdial usually is able to find the modem and connect and I can get online no problem. That's the good part.

However, after some amount of time (sometimes just a few minutes, sometimes hours, but it always eventually happens) the modem stops working and gets into a state where when I run wvdial it keeps looping and failing with:

Code:

ATDT*99#NO CARRIER--> No Carrier! Trying again.--> Sending: ATDT*99#

[code].....

Interestingly enough, when it's in this state I am still able to access the modem, and via AT commands am able to see that it has signal, can make phone calls, and can send SMS messages! It just can't seem to dial a data connection. Now, unplugging and plugging the modem back in almost always seems to solve this problem, only for it to fail randomly at some undetermined point in the future.

Why can't I just keep unplugging and replugging the modem, you ask? Because the computers (yes there are currently 9 computers and modems I need this to work on) are being deployed to clinics and offices in rural Africa where they will be locked in a box so they aren't stolen. I have pursued ways to shutdown power to the USB port in order to "fake" a hard pull of the cord in software, but haven't been successful so far. I've also tried reading as much as I can on the NO CARRIER response, but so far it's not turned anything up.
